Application filed January 17, 1396. Serial No. 575,912. (No model.)

To @Z3 zt'tomt 771160,17/ concern.'

Be it known that I, RUSSEL G. IVOODWARD, a citizen of the United States,residing at I'Vaukegan, in the county of Lake and State of Illinois,have invented certain new and useful Improvements in Sewing-Machines, ofwhich the following' is a description, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to sewing-machines, and particularly to what isknown as the Union Special Double Interlock Machine, in which twoneedles cooperating with a single nnder-thread-carrying looper arensed,A

together with two thread-carrying fingers reciprocating back and forthacross the line of the seam and depositing cross-threads which aresecured to the fabric by the rows of stitches made by the needles andthe looper.

The invention consists in certain improvements in the presser-foot, inthe means for operating it, and in various' other matters hereinafterdescribed, and referred to in the appended claims, which makes themachine with these parts applied particularly useful in sewing aroundthe edges of small cylindrical bodies, such as small stockings and thelike.

The invention is illustrated in the accompanying drawings, in which-Figure l is a front elevation of so much of a double interlockedsewing-machine as is necessary to a complete understanding of myinvention. Fig. is a plan view of the clothplate slide provided with myimproved means for operating the presser-foot. Fig. 3 is a sideelevation of the presser-foot; Fig. 4, a plan view thereof; Fig. 5, aview of a peculiar form of thread carrying finger which forms a part ofthe present invention.

In the drawings, A represents a portion of the base of a doubleinterlock sewing-machine.

B is the gooseneck; C, the needle-lever; E, the needle-bar carrying thetwo needles 0, a. h is the looper operated from the needle-lever by thelooper-rod c.

F is the cloth-plate slide, herein shown as hinged to the bed-plate G;but it will be understood that it may be made to slide in groovestherein, and I-I is the presser-foot attached to the presser-bar I inthe usual way by having its shank sleeved and clamped upon said bar. Thescrew c, which clamps the shank of the presser-foot upon the bar, isprovided with an extension, t-he under side of which is adapted toengage a pivoted thumb or finger lever g, pivoted to the vertical part hof an angle-piece K, pivoted to the cloth-plate slide and adapted tohave limited movement horizontally7 between the stops This affords alifting device by which the presser-foot is conveniently raised wheneverthe article to be sewed is placed on the machine, and has been devisedfor the reason that it is inconvenient on a machine of this character'to attach one of the ordinary footlifting devices to the presser-bar.lVhen it is desired to move the cloth-plate slide, the lever is swunglaterally on the pivot of the angle-piece K to disengage saidpresser-foot from the under side of the screw.

L L' are the laterally-swinging thread-carrying fingers which laycross-threads back and forth between the rows of stitches on the uppersurface of the fabric, and while the finger L is of ordinaryconstruction I have formed the linger L of special shape, as shown, toprevent the finger in its lateral motion from crossing over too fara-ndforcing back the edge of the article to be sewed. This construction offinger is useful in connection with the special form of presser-foot nowabout to be described and which forms a further improvement in machinesof this character. This presser-foot II has upon its front end a keel oriin Z, which registers with the slot in the throat-plate M in advance ofthe stitchforming mechanism, and this keel forms a guide for the edge ofthe fabric. Upon the left of the forward end of the foot extends aprojection or horn m, which provides a convenient means for holding downthe edge of the goods, and upon this horn the article to be sewed isturned and directed back toward the operator. Instead of feeding thearticle straight through the machine it is desirable, as just intimated,to move it around at a straight line, and to accomplish this re- IOOsult the presser-foot at the point where it is attachedk to the shank isalmost entirely cut away. Projecting vertically from the presserfoot isa guard n, formed as shown, which prevents the needles from stitchinginto the article being sewed. The presser-foot is provid ed with atongue o, which is a convenient but not absolutely essential feature. Bythe use of this foot it is possible to sew the edge of a closed tubewith an ornamental stitch, which it has not been heretofore possible todo upon a iiatbed machine.

It will be understood that I do not wish to be limited to the exactconstruction of sewing mechanism herein shown and described, as anyother machines making a cross-stitch may be substituted therefor, or Imight use an overedge stitch-forming mechanism.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

I.. In a sewing-machine, a presser-foot, a base-plate, a lever pivotallyconnected to the base-plate and pivoted to swing vertically and alsopivoted to swing horizontally on a vertical axis, with means on thepresser-foot with which the lever is adapted to engage; substantially asdescribed.

2. In combination with the cloth-plate slide, an angle-piece K havingthe vertically-proj ecting portion and having its horizontal partpivoted to the cloth-plate slide and having a= limited horizontalswinging movement on said pivot, a lever pivoted to the vertical portionof the angle-piece and adapted to engage the presser-foot to'lift thefoot; substantially as described.

3. In a sewing-machine a presser-foot having an opening for the passageof the needles and provided with an opening in rear of the needles inline therewith whereby the goods 1 after being sewed may be passed upthrough said opening and deflected toward the front of the machine;substantially as described.

4. The herein-described machine for sewing the edges of tubular articlescomprising stitchforming mechanism including two verticallyreciprocatingneedles and complemental stitch-forming mechanism, of a presser-foothaving an opening for the passage of the needles and having avertically-projecting guard in rear of said needles and a cut-awayportion in rear of said guard whereby the edge of the tube may be fed ina straight line, said presserfoot being provided with a tongue arrangedina plane between the needles; substantially as described.

5. A presser-foot for sewing-machines having a laterally-extendin ghorn, an opening for the passage of the needle or needles, avertically-projecting guard in rear thereof and a cut-away portion inrear of said guard; substantially as described.

In testimony whereof I ailix my signature in presence of two witnesses.
